As I said in another thread I thought Twilight was better. I think the first part of New Moon is boring, I don't like Jacob either so all his shirtless scenes did nothing for me what so ever. The second part is very good though and makes up for the boring first half.
There are quite a few cheesy scenes which made me and loaRAB of other people laugh, the acting isn't great even though Kristen Stewart has vastly improved since Twilight. The chemistry between Jacob and Bella is non existant, but on the plus side the chemistry is great between Bella an Edward (probably a result of real life romance, not great acting though) and the action scenes are excellent.
Overall I'd give it a 7.5/10, where as Twilight I'd give a 9/10.
